Detail in the visual display - The data base problem
Abstract
The types of simulations which can be presented to aircrew trainees are reviewed, along with the current state of the art in databases for presenting computer generated imagery (CGI). Simulation capabilities of systems that feature actual images of real objects, digitally stored data used to construct specified scenarios, and unit stored processes are summarized, along with empirically-defined resolution requirements to provide the eye with sufficient detail to elicit actions which mimic those expected in the real world. Tricks such as texturing, the insertion of unresolved detail, and upgrading the speed of image evolution through access to photographic data are being used to exploit the otherwise poor resolution of CGI. Although CGI offers the best options for simulations, the quality of the simulation still resides on the costs and size of the accessible database.
